Singles Day rakes in cash and surgical simulators get the Hollywood touch.

Here's your tech top 3 and what you need to know this week.

Singles Day in China brought in a whopping 14 billion dollars worth of goods sold. The shopping day, held on 11/11 started in 2009 as an attempt to get customers who are single to buy themselves gifts. The 24 hour event shattered records. In the first 90 minutes 5 billion dollars of goods were sold, compare that 18 billion, which was Amazon's revenue for the entire last quarter. At its peak there were 140,000 transactions per second.

Luxury watch maker Tag Heuer moved into the smartwatch market with a watch of its own. At 1,500 dollars it's similarly priced to its other watches, but significantly higher than mainstream competitors. The face of watch can change and receive alerts and reminders from a paired Android phone. The battery will last for 25 hours. If you don't like the watch Tag Heuer said it would convert it into a mechanical one.

After hurling insults at wireless competitors, T-Mobile CEO John Legere said that on a select number of streaming video services, data caps would be removed for users. Called Binge On, the service delivers unlimited 480p video from about 2 dozen services including HBO, Netflix and Hulu, but not YouTube. If you need higher quality you can turn the service off and use paid LTE. T-Mobile serves 302 million Americans so network congestion is a real possibility.

In focus we take a closer look at some amazing medical technology that is helping save lives. Surgeons learn by doing, but the stakes are high when it's life or death. New surgical simulators from Boston Children's Hospital have a bit of Hollywood magic to make them look and feel more real. The simulator group teamed up with Hollywood Special effects studio Fractured FX to make the simulators more lifelike. The team built two simulators. One is for surgeons to practice a difficult procedure inside an enclosed space in a brain and the other is heart lung bypass.

And they need to go on heart lung bypass at the bedside, emergently often during CPR. The current training model for those patients, if you call it that, is the patients themselves.

The models are built using CT scans from anonymous medical records so that they can be as real to life as possible. Seeing the models first hand I was amazed at how real they seemed. On this one each hair follicle is individually placed. These simulators will go through trials at Boston Children's Hospital and eventually be commercialized. I'm Nick Barber and that's a wrap.
